Hmmm. What's the average file size? While my viewers support files in memory, and my device has 128MB, I prefer to keep all books on a card.
I have about 3,500 ebooks all told on my PDA, occupying about 1.7GB spread across two 2GB SD cards.
Most (about 3,200) are in Plucker format, converted from HTML. I use the High Compression option, which uses a Palm OS port of Zlib for gzip compatible compression . Compression averages about 70%. (If I didn't, the Plucker documents would fill a 2GB card entirely, and slop over onto another. The default Plucker document uses Palm DOC compatible RLE compression, for compression ratios of about 40%.)
I also have several hundred in Mobipocket format, using Mobi's default compression, which is equivalent to PalmDOC, and a scattering in eReader, PDF, and plain text format.
I roll my own Plucker documents, and use a naming convention of <Author's Initials> <series # (if the book is part of a series)> <Title>, and set the default sort to Filename. Plucker doesn't support nested directories (though it's been discussed on the Plucker dev list), so Palm OS categories are used to breakdown by general topic. For Mobi, I'm at the mercy of the name used when the file was created. though Mobi offers Reading Lists that work like categories so I can control which books get shown in a listing.
The PDF viewer and the plain text viewer both support nested firectories, so I can use those for categorization.
File size varies widely here. I'd guess the average at about 300KB, but I have Plucker volumes as large as 15MB. (Big books, with lots of embedded color illustrations.)
